Hey Mike, hope you had a nice vacation.

I have not seen it anywhere, including your own site. What is the recommended setup (hardware list) and what should it weigh with that setup? What are the variables that may make the weights inconsistent? We need a goal... and reason to question our builds. In three planes, our AUW varied from 13.8 to 14.6 ozs (all with TP1320 and other parts the same). This is a long way from the weights others boast... should we question the accuracy of their scales? 0.8 oz variation sounds minute, but that is really significant (nearly 6%) when the only variable I can see is how much epoxy we use from one to the next.

I have to say, even at these apparently high weights, the plane performs extremely well. Fairly agressive climb out of a hover, and hovering just over half stick. I can only imagine how much better it would be to shed 2-3 ozs.

Regarding the wing twist... I assume you have seen this if you are trying to address it. I know, I am flying it too fast, but as a novice to 3D, it gets away from you now and then, particularly on down-line exits. That's how I munched mine, coming out of an inverted flat spin. If this happens in a dive, cutting the throttle is not enough to offset the aceleration of the dive. When it happens, control seems to be very latent and unresponsive.

After the repairs, I saw it twist again flying level and straight away from me at low altitude. It was weird to see the top wing contorted all out of place. That's why I added the stiff vertical member to the back of the cabane. That was a good fix, but probably not as good as a second set of crossing fly wires to box in the wings. I didn't have any extra CF rods, nor was there a good anchor point for a second set towards the rear of the lower wing. It flies again, but with a good bit of fibertape. As many have said, this plane does not crash well... but that's the tradeoff for lightweight and great performance. We just gotta learn to be better than gravity.

Kudos on a great aircraft... keep up the good work. We tell everyone what a great ship it is, and go buy one!
